SYNCPOINT in response to ISSUE PREPARE

Figure 1 shows an EXEC CICS® SYNCPOINT command being used in response to EXEC CICS ISSUE PREPARE on a conversation. Figure 1 also shows the conversation state before each command and the state and EIB fields that are set after each command.

Note that you can use also an EXEC CICS ISSUE PREPARE command in pendreceive state (state 3) and pendfree state (state 4).

Note also that, although the EXEC CICS ISSUE PREPARE command in the figure returns with the conversation in syncsend state (state 10), the only commands that are available for use on that conversation are EXEC CICS SYNCPOINT and EXEC CICS SYNCPOINT ROLLBACK. All other commands abend ATCV.
